Molecular Epidemiology Case-Series Study of Non-Small Cell Lung Cancer in Smoking and Non-Smoking Women and Men

Trial Conditions

Lung Cancer

What is the purpose of this trial?

RATIONALE: Studying samples of blood and tissue from smokers (closed to entry as of 7/15/07)
and non-smokers with cancer in the laboratory may help doctors learn more about changes that
occur in DNA and identify biomarkers related to cancer. It may also help doctors learn more
about risk factors for lung cancer and may help the study of cancer in the future.
PURPOSE: This clinical trial is studying carcinogens in lung tissue from smokers (closed to
entry as of 7/15/07) and non-smokers with newly diagnosed stage I, stage II, or stage III
non-small cell lung cancer.
